Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify.</em>
f(x) = x² + 9x - 6
<u>Step 2: Evaluate</u>
- Substitute in <em>x</em> [Function f(x)]: f(-x) = (-x)² + 9(-x) - 6
- [Order of Operations] Simplify: f(-x) = x² - 9x - 6
Answer:
12
Step-by-step explanation:
Assume that lines which appear to be tangent are tangent.
Therefor this is a right triangle.
Use the pythagorean theorem
c^2 = a^2 + b^2
15^2 = ?^2 + 9^2
225 = ?^2 + 81
subtract 81 from both sides
144 = ?^2
Take the square root of both sides
12 = ?
